Description

The present invention relates to a hydroponic cultivation apparatus centered on a foamed polystyrene board, which allows a person who does not have special knowledge about agriculture to perform hydroponic cultivation inexpensively and easily.

Among plant cultivation methods, hydroponics is used to improve the shortcomings of cultivation methods using ordinary soil. Specifically, hydroponics includes water leveling that is cumbersome and affected by weather conditions, ease of nutrient management and soil property management, prevention of pests and diseases, and increase in cropping regardless of the season. It is made possible by cultivation. As a result, root growth stress due to soil is excluded, and growth promotion and yield increase are realized, making it easy to grow pesticide-free cultivation with extremely high added value in the market.

Such hydroponics are mainly large-scale facilities for agricultural corporations except for houseplant cultivation (hydroculture) for home use, and have achieved high productivity in combination with house technology and factory equipment. For example, methods such as circulating water with a dedicated pipe or spraying a solution to prevent root rot have been taken. All of these are optimized for plant growth, and a stable yield can be obtained in a short cycle, and pesticide-free cultivation is relatively easy.

In addition, in any hydroponic cultivation apparatus, a plant seedling cannot be floated directly on the water surface, but a part for fixing the plant is required. About this method, the existing hydroponic cultivation apparatus is roughly divided into the following two types. That is, (A) A hole in a pipe for circulation of liquid fertilizer and the plant is fixed directly in the hole, (B) A plant that is sown in a sponge-made sheet and the sheet is floated on the liquid fertilizer It is.

Moreover, when the focus is shifted from production to consumption, the importance of food safety has been increasing recently. This is not limited to retail businesses for general consumers, but is also observed by restaurants and food businesses that use plants as raw materials. There is also an interest in small-scale, safe and simple plant cultivation in the home, starting with the home garden. This change in demand is a tailwind for hydroponics.

Since existing hydroponics technology requires a combination with various technologies and is low in versatility and requires a large amount of initial investment, hydroponics are limited to businesses that are mainly large corporations. Has also been limited to some edible vegetables. Therefore, it cannot fully respond to the change in demand. Cultivation using these facilities is currently costly and tends to be less profitable.

Speaking of versatility, (Exhibit) The type of equipment in which holes are drilled in pipes for liquid fertilizer circulation and plants are directly fixed in the holes requires completely dedicated equipment for each factory or house, and the smallest scale is large. Once installed, it is difficult to change the overall configuration. In addition, cultivars are also limited due to pipe shape restrictions.
(B) Even if the plant is sown on a sheet made of sponge, etc. and the sheet is floated in liquid fertilizer, once the facility is laid, the shape of the cultivation sheet is fixed, so to maintain profitability It is necessary to operate on a large scale in a short cycle. In addition, if the production volume is adjusted by lowering the density of seedlings planted on one sheet while maintaining the size of the sheet, there is a problem that the generation of algae is induced from the part where the seedlings are thinned out. . Therefore, the cultivars that can be cultivated were limited due to constraints such as cycle to harvest and seedling size.

On the other hand, in both cases (B) and (B), it is necessary to combine with other equipment to optimize plant cultivation, and the initial investment will increase. For example, it required house equipment and factory equipment for keeping the temperature constant, or factory equipment for maintaining lighting.

In this way, dedicated equipment with no versatility is expensive, so flexible operation is avoided and profitability tends to be low. At the same time, commercial hydroponics has been limited to large-scale business owners due to restrictions such as minimum scale and initial investment.

As for small hydroponics for individual consumers, special design, complicated mechanism, and high price have become obstacles (the former), and facilities that have been miniaturized and simplified have not spread. Several attempts have been made to apply (B), but this hinders high prices for optimizing various elements such as lighting and shapes to prevent algae, and this also responds to vigorous demand. Not in.

In view of the current situation, the present invention aims to solve the problem of hydroponics, which is low in versatility of equipment and expensive. At the same time, the goal is to overcome the current situation of hydroponics, which is difficult to implement without special knowledge about agriculture, such as algae can only be prevented with complex equipment.

The hydroponic cultivation apparatus of the present invention is a hydroponic cultivation apparatus characterized by using a foamed polystyrene board with a through hole as a base for fixing seedlings. The foamed polystyrene plate has a plurality of through holes at equal intervals in one sheet, and a cylindrical foam polystyrene having the same shape as the through holes is also attached, so that the holes can be closed and used.

As a hydroponic cultivation device, the foamed polystyrene is floated in a tank filled with liquid manure, and a sponge with a notch that can easily penetrate water is selected depending on the size and number of plants. It becomes the foundation of cultivation by combining with.

At the same time, the expanded polystyrene is colored not only in general white but also in other colors.

The hydroponic cultivation apparatus using the expanded polystyrene of the present invention can adjust the interval between holes according to the size, growth stage or cultivation density of the plant to be cultivated. Therefore, it is possible to flexibly change the cultivated variety without replacing the hydroponic cultivation apparatus.

In addition, the foamed polystyrene having a function of closing the hole is versatile, and it is not necessary to change the shape of the foamed polystyrene in accordance with the final usage pattern. Therefore, for any product, there is only one type of polystyrene foam mold, and it is not necessary to make a special order individually, and it can be provided at a low cost.

The unused holes can be closed with the same cylindrical foamed polystyrene, and the water surface of hydroponics is not directly exposed to light, so the generation of algae can be suppressed.

Furthermore, since it can be colored in black and gray in addition to white, it is possible to maintain an overwhelmingly clean appearance even if algae grows.

As a result, non-chemical hydroponic cultivation can be easily performed at home, and small-scale hydroponic cultivation can be performed in small stores such as cafes. In any case, the use of pesticide-free vegetables is facilitated.
